Background DNA vaccines are a good option to generate a desired antigen using the cellular machinery of the vaccinated subject. This kind of vaccine can induce both of the humoral and cellular immune response, and show high stability and easy working, as well as offer a low-cost production. and safety for immune compromised patients [1]. However, some disadvantages, such as the low transfection...
several strains of saccharomyces cerevisiae were isolated from different sources. these strains were under taken for ethanol tolerance analysis and growth under stress condition. exponential phase to various concentrations of ethanol (2–26% v/v) for 1 h was used for isolation of resistant strains. viable cells were isolated and purified by inoculation of diluted samples on yeast extract peptone...
background: glutathione (gsh) is a non-protein thiol compound, which plays an important role in the response to oxidative stress and nutritional stress. the aim of this study was to isolate indigenous s. cerevisiae strains capable of effectively produce gsh. methods: one hundred-twenty sweet fruit samples were collected. the strains were isolated on yeast glucose chloramphenicol (ygc) agar medi...
the hepatitis b surface antigen ( hbsag) gene was isolated from an iranian hbeag positive carrier by pcr. the gene was cloned in puc19 for sequencing and pyes2 for expression in saccharomyces cerevisiae, which pnf1 and pdf3 constructs were made respectively. the sequencing data showed that the isolated hbsag gene shared more than 90% homology with the ayw subtype. the pdf3 was transferred into ...
The aim of this study was to investigate the effects of saccharomyces cerevisiae yeast and butyrate monoglycerides on the performance, blood parameters and nutrients digestibility in suckling Holstein calves. For this experiment, 32 newly-born Holstein calves (average age 1-8 days; average weight 38±1 kg) were used in a completely randomized design with 2×2 factorial arrangement, 4 treatmen...
Background & Objective: Citrinin mycotoxin is produced by filamentous toxin producing fungi. Saccharomyces cerevisiae yeast has the ability to bind mycotoxins to its cell wall and thus reduce its toxicity. The aim of this study was to determine the amount of Citrinin mycotoxin and its reduction in wheat flour by Saccharomyces cerevisiae. Method: In this study, 15 samples of wheat flour were...
Vitamin D deficiency causes osteoporosis, osteopenia, fractures, rickets and more recently is linked with some chronic illnesses such as cancer. Because of the safety and probiotic properties of the yeast Saccharomyces cerevisiae, we hypothesized that yeast cells enriched with cholecalciferol (vitamin D3) could represent a solution for prevention or treatment of vitamin D deficiency. In this st...
the potential of heat inactivated saccharomyces cerevisiae in the bioremoval and reduction ofcr (vi) ions from wastewaters was evaluated in terms of metal uptake in time and at equilibrium, andbiosorption efficiency, by varying ph, biosorbent doses, contact time and temperature, in batch mode. during the sorption process, the heat inactivated biomass of the yeast saccharomyces cerevisiae is cap...
